Question

Suppose you want to investigate whether the type of music

students listen to while studying can affect their test
scores.
Which statement represents a valid hypothesis about music and studying?
OA. If you listen to calming music while you study, then you are more
likely to feel calm during the test.
B. Does the type of music played while studying affect test
performance?
C. Students who listen to music with faster beats while studying
perform better on tests.
D. Most people prefer pop or jazz music when studying for a test.

Answer 1

Answer: C because it is a testable hypothesis. For instance you could only listen to one genre for a term and another for the next term and then compare your scores.

Explanation: A is incorrect because you can not test a feeling like how calm you are.
